PSU Schematic advice needed for 6SN7 line stage preamp

Hello friends,

Many years in ago, in 2006, I built this 6SN7 preamp. I sourced the schematic from the late Wim Bouwman (Mr Valve) in South Africa. I used the preamp with a solid state power amplifier, and it sounded really good. The gain was somewhat high though.

I have lost my notes on the project, and cannot seem to find satisfying info on a simple yet effective power supply design for this build.

Below is are pictures of the schematic.

Could any of you tube aficionados point me in the right direction? It would be much appreciated.

Thank you in advance,
Christian
